This article addresses the common question, “What should I do if v2rayNG won’t connect?” It focuses on troubleshooting your phone’s network, imported nodes, system permissions, and client settings. It’s intended for beginners who have just installed v2rayNG or imported free nodes or a subscription but can’t connect. Follow the steps below to check for common issues.
1. First, make sure your basic network connection is working
Many connection failures aren’t caused by v2rayNG itself, but by an unstable network. First, close v2rayNG and open a browser to visit a domestic website. Check that you can access the internet over Wi-Fi or mobile data. If domestic websites won’t load either, troubleshoot your phone’s network, router, or carrier signal first.
If you’re using public Wi-Fi, a company network, or a campus network, ports may be restricted or proxy traffic may be blocked. Try switching to mobile data. If you can connect over mobile data, the problem is most likely with your current Wi-Fi network.
2. Check that your nodes or subscription are working
The most common reasons v2rayNG won’t connect are an inactive node, an expired subscription, or an incomplete configuration. Free nodes in particular can be unstable depending on the condition of the network routes, so it’s a good idea to have several nodes to test.
- Open v2rayNG and make sure your nodes or subscription imported successfully.
- Long-press a node and select “Test current service status” or a similar test option.
- If several nodes time out, update your subscription first. If only one node fails, try another.
- When getting free nodes from this site, make sure you copy the entire link, including all characters at the beginning and end.
If you imported a subscription link, open the menu in the upper-right corner and select Update subscription. If the update fails, the subscription URL may be unavailable, or your current network may not be able to access the subscription source.
3. Check system permissions and the VPN connection prompt
The first time you connect with v2rayNG, Android will show a VPN connection request. Tap Allow. If you accidentally tapped Deny, find VPN or app permissions in your system settings and grant permission again. Once connected, you’ll usually see a key or VPN icon in the status bar.
On some phones, battery saver mode restricts background network access, causing v2rayNG to disconnect soon after connecting. Add v2rayNG to the battery optimization whitelist and turn off any background restrictions for the app. If you have a security or firewall app installed, make sure it isn’t blocking v2rayNG.
4. Check the time, DNS, and routing mode
An incorrect phone clock can also cause TLS-related connection failures. Turn on “Set time automatically” and “Set time zone automatically” in your system settings. If only certain apps are inaccessible, check v2rayNG’s routing settings. Start with the default configuration to avoid accidentally routing only some traffic through the proxy.
- Incorrect time: Turn on automatic time and restart the client.
- DNS issues: Switch between Wi-Fi and mobile data, or restart your router and try again.
- Routing rules changed by mistake: Restore the default routing settings and reconnect.
- Incompatible node protocol: Make sure you have a recent client version and update v2rayNG if necessary.
5. Quick troubleshooting summary
Try these steps in order: First, make sure your phone can access domestic websites. Then compare your connection over Wi-Fi and mobile data. Next, update your subscription and try a different node. After that, check VPN permissions, battery restrictions, and system time. Finally, update v2rayNG or reimport your configuration. This can save you from repeatedly uninstalling the client as a first resort.
If none of your nodes can connect but your network is otherwise working, the subscription source may be unavailable, the nodes may be inactive, or your current network may have strict restrictions. Try a different set of nodes or try again later. Avoid frequently changing advanced settings you don’t understand; the default settings are best for beginners.
